Abstract (en)
[origin: EP0320228A2] Formation of solid and/or high boiling residues during the isomerization of one of 1,4-dichlorobutene-2 and 3,4-dichlorobutene-1 into each other in the presence of a cuprous chloride catalyst is inhibited by the addition to the isomerization reaction of a small amount of a hydroxylamine salt.
